I bought mine at Rob's R/C Hobbies (http://www.robsrchobbies.com/), and he had it for the same price as Tower. He has both the 5.5 and the 6.5. Website is a little weak, so call him. Ask for Rob or Michelle, his wife if you do call. (BTW, check out the website pricing he has on the Hyper 7 PBS!)
The Novak is a LOT cheaper than the Neo One/Sphere combo, but runs a bit different. Real fast, very sensitive to throttle input. I am still trying to figure out how to de-program the drag brake. The directions are not exactly clear on this, although they do take you step by step through it.
